(o 137-20) This invention relates to improvements in 12 and isexternally threaded as at 13, which ex- 7 creamers and has particularreference to a device tends through the plate 7 and engages a threadedfor removing cream from the top of a standard fitting 14. The extremityof the externally milk bottle. threaded end is serrated as shown at 16so as to A further object is to produce a device which prevent a ball 17from sealing the externally is economical to manufacture. threaded endas will be later described. ;This

An additional object is to produce a device ball 17 rests upon a seat18. An intake tube 19 which may be readily cleaned. is secured to thebottom. of the fitting 14. This A still further object is to produce adevice intake tube has ports 21 formed on opposite wherein only thecream will be taken from the sides thereof and at a point above thecream line 65 bottle, and one which will not create currents when thedevice is'inserted in thebottle as shown which would otherwise mix thecream with the in Fig. 1. v milk. A bulb 22 is attached to theportion-23 of the Other objects and advantages will be apparent Y-shapedmember 11. The opposite end of this during the course of the followingdescription.

This prevents a check ball 28 from closing Fig.1 is a fragmentary view of an upper porthis tube as will be laterdescribed. This check tion of a milk bottle shown in cross section andball 28 rests upon a seat 29, the purpose of which having my inventionpositioned in the top of will be later seen. the bottle, 7 f Assumingnow that the device is placed in a a Fig. 2 is a fragmentary detail viewdisclosing bottle, as shown in Fig. l, andvthe bulb 22 is v th str ctionof my device, pressed, air within" the bulb will be passed down- Fig. 3is a fragmentary view showing the Wardly through the portion 23 of theY-shaped position of the valves within the tube, member, will contactthe ball 17 resting upon its Fig. 4 is a fragmentary side elevation ofthe Seat 18 and therefore as it cannot escape downdischarge tube showingthe serrated edge, and Wardly this'air will raise the valve 28 off ofits Fig. 5 is a cross sectional view onithe line 55 seat and will'thenpass through the pipe 26. Due

Due to the fact that milk is ordinarily bottled it will be impossiblefor the ball to seat itself several hours before delivery orconsumption, against the end of the pipe, and thus close off thesuflicient time elapses for the. cream to separate escape for the air.As soon as the air has been 35 and ris to the top of the bottle.
